Jubel is a bit of both. Overall I'd say he's very agile. When he gets to run around off leash in the woods I've gotten many comments about how agile he is as he leaps over logs, runs along the top of fallen trees, makes sharp turns, and quickly scales steep inclines. On the other hand he can spazz out with zoomies in the house and trip on stairs, slam into walls and furniture but never misses a beat. Runs on like nothing happened.
